Our company is trusted by the leading fintech leaders worldwide. These people have trusted us with their resources, and we proved them right. Here is the list of top leaders:
Fraud Is Evolving Faster Than Your Rules Engine
The fraud landscape has entirely changed. What worked in 2019 is not working now, and the gap keeps widening.
Each fintech platform today encounters a specific and evolving set of fraud types. Account takeover (ATO) attacks increased 122% year-over-year in 2025, targeting fintech platforms alone (Sift Digital Trust Index). Synthetic identity fraud, where fraudsters create fake personas using real and fabricated data, crossed $35 billion in the US in 2023, according to FiVerity, cited by the Federal Reserve Bank of Boston. That's before counting card fraud, payment fraud, money muling, and first-party loan fraud.
The fraud types hitting fintech platforms today:
- Account Takeover (ATO) via credential stuffing and phishing
- Real-time payment fraud and authorized push payment (APP) scams
- Synthetic identity fraud at onboarding
- Card-not-present and chargeback fraud
- Money laundering through layered transactions
- Lending fraud first-party bust-out schemes
Legacy rule-based systems were not created for how fintech platforms actually operate. A neobank onboards users remotely across various channels simultaneously. A BNPL platform processes thousands of checkout transactions per second across various merchant categories and geographies. A lending platform receives application bursts from affiliate channels with no prior user history. Rule engines fail to understand channel diversity, interpret velocity patterns, or analyze cross-product behavior - they fire on fixed thresholds and miss everything in between. The result: fraud slips through in patterns the rules don't cover, and legitimate customers get blocked for unusual but genuine transactions. Manual review queues back up and add latency that digital-first fintech customers won't tolerate.
Machine learning doesn't require predefined rules to catch fraud; it learns what normal behavior looks like across millions of transactions, then flags what doesn't fit. That shift from reactive rules to predictive models is the reason AI fraud detection in fintech has become the standard for any serious platform.
The fraud types hitting fintech platforms today:
- Supervised learning to detect known fraud patterns with high accuracy
- Unsupervised anomaly detection brings out novel attack types before they spread
- Graph neural networks map fraud rings and money laundering networks that are invisible to single-transaction analysis
- Adaptive models retrain constantly on new fraud signals - no manual rule updates
- Behavioral biometrics catch account takeovers from how a user types, scrolls, and navigates, not only what credentials they enter
- False positive rates come down notably, diminishing customer friction and abandonment
- Real-time risk scoring on each transaction in under 100ms
According to McKinsey, companies deploying advanced fraud analysis reduce false positives by 20-50% and improve detection rates by 15-20%, while boosting customer satisfaction scores. Those are not marginal gains; they translate directly, at scale, into revenue protection and reduced operational costs.
AI Fraud Detection Services We Build
We don't implement one-size-fits-all fraud tools. Every service below is built around your transaction volume, platform type, and regulatory environment.
Not Sure Which Service Fits Your Platform?
Tell us your platform type and fraud challenge. We'll scope the right detection stack for you — no commitment, no pitch deck.

Key Features of Our AI Fraud Detection Solution
We prioritize the components that matter most to your risk teams, engineering team, and compliance officer - all in a single production-ready AI fraud detection software your platform can deploy via API.

Real-Time Risk Scoring Engine
Scores each transaction in under 100ms using multi-dimensional signals - amount, location, device, network context, and velocity behavior before settlement.

Machine Learning Models
Custom supervised, semi-supervised, and unsupervised ML models trained on your transaction data. These include isolation forests, graph neural networks, and gradient boosting for network-based fraud.

Behavioral Biometrics & Device Intelligence
Continuous profiling of swipe behavior, typing patterns, device fingerprints, and session flow. It detects account takeovers, remote access tools, and bot activity that static auth checks miss.

Explainable AI (XAI) & Compliance Dashboards
Every fraud detection includes a human-readable explanation of why it was flagged - crucial for regulatory audits, customer dispute resolution, and internal reviews. Full audit trail maintained.

Low False Positive Rate
False declines cost you, customers. Our models are calibrated specifically to reduce false positive rates, using feedback loops and threshold tuning from your review team.

Multi-Channel Coverage
Single detection layer across web, API, mobile, and partner channels. It covers login, onboarding, transaction initiation, and post-transaction monitoring from one unified risk engine.
Who Needs an AI Fraud Detection Solution?
If your platform moves money, holds customer funds, or lends money, you need a fraud detection layer that goes beyond rule-based systems. Here's where we witness the biggest gap.
Neobanks & Digital Banks
Remote onboarding, high-volume account creation, and no branch verification are exactly what synthetic identity and ATO fraudsters target. You need behavioral and document-level defenses from day one.
Payment Gateways & eWallet Platforms
Every millisecond of payment processing carries fraud risk. Real-time risk scoring and chargeback prevention are non-negotiable for platforms managing high transaction volumes.
Lending & BNPL Platforms
First-party loan fraud and bust-out schemes look legitimate until repayment time. ML-based application scoring catches intent signals that credit bureaus miss.
Crypto & DeFi Platforms
Cross-chain activity, pseudonymous transactions, and mixer services create unique AML blind spots. Graph analytics and on-chain behavior monitoring are the right tools here.
Insurance & Trading Platforms
Premium manipulation, claims fraud, and wash trading all leave behavioral patterns that AI detects. Especially valuable where human review queues are the bottleneck.
Our AI Fraud Detection Development Process
We scope, develop, and deploy fraud detection systems end-to-end, from understanding your fraud landscape to continuous post-deployment model enhancements. No black boxes.
Fraud Risk Assessment & Discovery
We map your platform's attack surface by user base, transaction type, and channel. We review your false positive rates, current fraud losses, review queue volumes, and compliance requirements before starting with code.
Data Pipeline & Feature Engineering
Fraud models are only as good as the features they run on. We build real-time and batch data pipelines, engineer transaction features, and enrich with device, behavioral, and network signals to give your models maximum predictive power.
Model Development & Training
We train and evaluate multiple model architectures - gradient boosting, isolation forests, neural networks, and graph models on your labeled transaction data. Models are validated against real fraud scenarios before deployment.
Integration & API Deployment
The risk scoring engine is deployed as a low-latency REST or gRPC API that integrates with your existing payment stack, mobile app backend, or core banking system. No rip-and-replace required.
Tuning, Calibration & False Positive Reduction
We run a calibration phase post-deployment, testing decision boundaries, adjusting model thresholds, and incorporating investigator feedback to optimize the precision-recall tradeoff for your specific customer base.
Ongoing Monitoring & Model Retraining
Fraud patterns drift. Models that are not retrained degrade. We provide ongoing monitoring dashboards, alert on model performance drops, and run scheduled retraining pipelines to keep detection rates high as fraud evolves.

Compliance & Regulatory Alignment
Fraud detection and compliance are not separate issues. Our systems are developed to meet the requirements of regulators in the US, UK, EU, and India, not only to catch fraud.
Global AML & Financial Crime Regulations
Our AML monitoring modules are created against the major regulatory frameworks your compliance team answers to. We maintain full audit trails and generate regulator-ready reports for every flagged case.
- FATF - Recommendations 10–16 on KYC, transaction monitoring, and beneficial ownership
- FinCEN (USA) - BSA compliance and SAR/CTR filing automation, with FinCEN direct filing support
- FCA (UK) - Alignment with the Financial Crime Guide and JMLSG guidance
- RBI (India) - KYC/AML master directions for regulated fintech entities
- EU AMLD6 - Sixth Anti-Money Laundering Directive compliance, including predicate offenses and criminal liability alignment
- PSD2 / Open Banking (EU & UK) - Strong Customer Authentication (SCA) compliance and fraud liability alignment under the revised Payment Services Directive
- Full audit trail, case history, and decision documentation for regulatory inspection


Data Privacy in Fraud Detection
Using biometric and behavioral signals for fraud detection increases privacy obligations. Our systems are built with privacy-by-design principles - purpose limitation, data minimization, and user transparency.
- GDPR-compliant data handling for EU users
- CCPA alignment for US-based platforms
- Behavioral data is processed and stored per the retention policies your compliance team sets
- No biometric data sold or shared with third parties
- Data residency controls for cross-border platforms
PCI DSS Compliance
For platforms handling cardholder data, our fraud detection layer is built to operate within the PCI DSS scope without creating a new compliance surface area.
- Tokenization of sensitive card data before processing
- Encrypted data transit and storage
- Access control and logging aligned to PCI DSS requirements
- No raw card data stored in fraud model training sets

Why Build Your AI Fraud Detection Solution With Us?
There are various fraud tool vendors and AI development companies, but very few deeply understand fintech to build a production-based fraud detection system.
Fintech-Specific Fraud Expertise
We have delivered 350+ fintech products - payment platforms, neobank apps, lending software, BNPL apps, and crypto wallets. Our fraud detection work is not generic. Our fintech specialists understand that a neobank's fraud surface looks entirely distinct from a BNPL platform, and we design and scope solutions accordingly. We map your attack vectors before we touch the model architecture.
Real-time Performance at Scale
Our risk scoring engines are developed for enterprise-ready throughput - sub-100ms latency, horizontal scalability on Kubernetes, and real-time Kafka-based event pipelines. If your platform processes millions of transactions daily, the architecture holds. We have created and tested at scale; we don't prototype and hand off.
Explainable, Auditable Decisions
Every fraud decision our system makes comes with a SHAP-based explanation: which signals drove the score, by how much, and why. Your risk analysts can review it, and your customer service team can act on it. That transparency is built into the system, not a dashboard bolted on afterward.
Continuous Model Improvement
Fraud patterns constantly change. A model trained today is less precise in six months if no one re-trains it. We develop a full MLOps pipeline - drift detection, champion-challenger testing, and performance monitoring, so your detection rates remain high without needing a new engagement every quarter.

What We Have Actually Built

ATO Fraud
Reducing Account Takeover Fraud for a Neobank
Client:
Digital neobank with 500,000+ active users, operating across three markets.
Problem:
Credential stuffing attacks were systematically testing leaked username/password combinations against the app at scale. The bank's existing rule-based system was catching fewer than 40% of takeovers and generating enough false positives that the customer support queue for locked accounts had tripled in six months.
Solution:
Nimble AppGenie deployed a behavioral biometrics and device intelligence layer on top of the existing authentication flow. Keystroke dynamics, swipe patterns, session navigation sequences, and device fingerprints were profiled per user. A dedicated ATO model was trained on confirmed takeover events and ran in-line at login. Step-up authentication was triggered only when risk scores exceeded calibrated thresholds, not on every login.
- 78% reduction in ATO fraud
- 40% fewer false declines
- $1.2M in fraud losses prevented
Payment Fraud
Real-Time Payment AI-Powered Fraud Prevention for a BNPL Platform
Client:
A fast-growing BNPL platform processing 50,000+ transactions per day across retail and e-commerce checkout flows.
Problem:
Payment fraud losses were running at 1.4% of GMV, nearly double the industry benchmark. The platform's rule-based fraud checks added 3–4 seconds to checkout, causing cart abandonment, and still missed fraud that came from newly created accounts with no prior transaction history.
Solution:
We deployed a real-time transaction scoring engine running gradient boosting and device intelligence models, with a latency budget of 80ms. New account cold-start fraud was addressed through application-level risk signals - device age, email domain risk, IP reputation, and synthetic identity indicators at sign-up. The model was trained on the platform's own fraud history and calibrated against their merchant dispute data.
- 61% drop in payment fraud losses
- Latency reduced from 3.4s to 80ms
- 22% improvement in checkout conversion

What Clients Say
Check the results from the live fintech platforms we have worked with. Client names are kept confidential per NDA - results are real.
We'd tried two rule-based tools before Nimble AppGenie. Neither could keep up with new attack patterns. Their ML model was live in eight weeks and caught patterns we hadn't even seen yet.
Head of Risk
Digital Neobank, UKThe false positive rate was our biggest problem — we were locking out real customers daily. After their calibration work, our false decline rate dropped by more than a third, and complaints went with it.
CTO
Payment Gateway Platform, USAWhat I valued most was that their team understood our compliance requirements — FinCEN, PCI DSS, the whole stack — and built the audit trail into the system from the start. Not as an afterthought.
Chief Compliance Officer
Lending Platform, IndiaYour Fraud Stack Should Be Working as Hard as Your Product Team
We have built fraud detection for neobanks, BNPL platforms, lending apps, and crypto exchanges. If you're still running rules, you're already behind. Let's fix that.

Frequently Asked Questions

Rules fire on fixed thresholds; they can't interpret context. AI models learn behavioral patterns across thousands of signals simultaneously and adapt when new fraud types emerge. The result is higher catch rates, fewer false positives, and no manual rule maintenance every time attackers change tactics.
A focused deployment, real-time transaction scoring on an existing data pipeline, goes live in 6–10 weeks. A full stack covering AML, ATO prevention, KYC fraud, and compliance dashboards typically takes 4–6 months. We give you an exact timeline after the discovery phase.
Yes. The risk engine deploys as a REST or gRPC API; no rip-and-replace required. We have integrated with Stripe, Adyen, Razorpay, and custom stacks. Sandbox environment and integration documentation are included in every deployment.
After calibration, our models typically run 30–50% fewer false positives than the rule-based systems they replace. We tune thresholds specifically to your customer base and transaction profile, not a generic benchmark.
Yes. GDPR and CCPA compliance is built into data handling from day one. The AML module aligns with FATF, FinCEN BSA/SAR, FCA Financial Crime Guide, RBI KYC/AML directions, EU AMLD6, and PSD2 SCA requirements with full audit trails on every flagged case.
Yes. We use on-chain behavioral analytics and graph neural networks to map wallet networks across chains, surfacing money laundering, mixer usage, wash trading, and rug-pull patterns. Output includes compliance documentation for regulatory reporting.
We build a full MLOps pipeline with drift monitoring, scheduled retraining, and champion-challenger testing. Your risk team's case outcomes feed back into training. The model improves continuously rather than degrading as fraud patterns shift.
